DIN-Compliant Industrial Graphite Sheets

Product Overview

Key Features Meeting DIN Requirements

1. Material Purity
   • Meets DIN 52900 standards for ash content (<0.2%) and sulfur content (<0.1%).
   • Free of halogenated compounds, aligning with DIN EN 61249-2-21 for electronic applications.
2. Thermo-Mechanical Properties
   • Thermal stability from -200°C to +3000°C (DIN EN 1356 standard).
   • Compressive strength of 50-80 MPa (DIN EN 13555) with <3% creep relaxation under 100 bar pressure.
3. Dimensional Accuracy
   • Width tolerance: ±0.5mm for 1000mm/1500mm rolls (DIN EN 13555).
   • Thickness uniformity: ±5% for 0.15-5mm sheets (DIN EN ISO 4784).

Applications in DIN-Compliant Systems

1. Flange Sealing
   • Used in ASME B16.5/DIN EN 1092-1 flange connections, providing leak-tight seals for gas, liquid, and slurry pipelines.
   • Composite variants with stainless steel inserts meet DIN EN 15149-2 for pressure equipment.
2. Valve & Pump Seals
   • Graphite packing rings for valves comply with DIN 3352, ensuring reliability in oil refineries and chemical plants.
   • Self-lubricating properties reduce friction in pumps adhering to DIN 24256 standards.
3. High-Temperature Insulation
   • Thick plates (1.0-5mm) used in furnace doors and heat exchangers, meeting DIN 1709 for thermal insulation.
